Patent number: 8398866Abstract: A microchip for forming an emulsion has a first glass substrate, a second glass substrate and a silicon substrate. The silicon substrate has formed therein a first fluid flow path through which a first fluid flows and a second fluid flow path through which a second fluid that is not mixed with the first fluid flows. The first fluid flow path has a plurality of branched flow paths that join at a joint portion. The second fluid flow path communicates with the joint portion. The silicon substrate has formed therein an emulsion formation flow path that faces an edge portion of the second fluid flow path at the joint portion. An emulsion composed of the first fluid and the second fluid that is surrounded by the first fluid is formed in the emulsion formation flow path.Type: GrantFiled: June 18, 2012Date of Patent: March 19, 2013Assignee: Dai Nippon Printing Co., Ltd.Inventors: Yutaka Ozawa, Ryoichi Ohigashi, Koji Fujimoto, Shoji Takeuchi

Patent number: 6089186Abstract: The invention provides a vacuum coating forming device for forming a thin-film coating by a plasma beam on a substrate arranged in a vacuum chamber, the vacuum coating forming device being provided with a pressure gradient type plasma gun for generating the plasma beam toward the vacuum chamber and a converging coil which is provided so as to surround a short-tube portion of the vacuum chamber projecting toward an outlet of the plasma gun and which reduces a cross section of the plasma beam. This vacuum coating forming device further comprises an insulating tube provided at the outlet so as to surround the plasma beam and project in electric floating state, and an electron return electrode which surrounds the insulating tube within the short-tube portion and which is higher in electric potential than the outlet.Type: GrantFiled: September 13, 1999Date of Patent: July 18, 2000Assignees: Chugai Ro Co., Ltd., Dai Nippon Printing Co., Ltd.Inventors: Kinya Kisoda, Eiji Furuya, Ryoichi Ohigashi
